Where should I work to make the most money as a crime scene investigator?

It is best to work with an agency that provides you the opportunity to become skilled in multiple disciplines (fingerprints, firearms, explosives, bodily fluids, criminal psychology, criminal pathology, etc.) and these are usually the agencies that serve a wider geographic region such as a county, state, or country. The wider the geographic coverage, and the wider the range of specialties, the more money you can make.
